I believe Tim learned a valuable lesson from the Provodnikov and Pac fights.

Bradley's ability to keep the jab in JMM's face, fight at his pace and distance while controlling most of the exchanges and his hand speed became icing on the cake. Bradley did not get over aggressive, make mistakes and leave himself in awkward/unbalanced positions, inside of JMM's wheel house. Although it was not near brillant, Bradley did exactly what you need to do as a fighter, to beat a brillant counter puncher/boxer like JMM. He used his speed (hands and footwork) to his advantage. Things he clearly did not do against Provodnikov and Pacquaio (although he did show more against Pac, but not enough).

I believe the combination of Bradley fighting an intelligent fight (as he did against JMM) along with the Pac's diminishing speed will make the difference.
